Advantages of this filter over the old K&N:
*Outflows the original K&N by around 20%
*Uses woven cotten cloth, like an oxford shirt, instead of cheesecloth, more uniform, more consistent filtration over life of the filter
*Uses a stainless steel mesh with epoxy coating to hold the filter media in place instead of aluminum screen
*The oil used on the filter is 100% synthetic, lighter than oils other companies use, which makes it harder to over-oil the filter and won't damage your sensors
*Features a barb around the perimeter of the filter which makes it lock securely into the housing. Any sort of sealing grease is no longer needed and the aluminum bracket across the top of the housing is no longer critical to hold the filter in place.
*Made in USA (America, smurf Yeah!)

Can these new filters be run without oiling them? What are the upsides and downsides of either/both? I've never been keen on oiling any of my intake air filters and just went ahead and bought a new one when the proposed cleaning time arrived. Maybe it's just the very old school still in me! Thanks.
